The Court also denied counsel's request to submit corrected filings.
- Why the court cared
- Fabricated: Case Law | Supplemental Filing contained forty-three identified instances of fabricated citations or case law; Court declined to consider the filing and treated those propositions as unsupported. || Fabricated: Case Law | Consolidated Complaint was 'replete with citations to irrelevant, and sometimes fabricated, case law' across many paragraphs; Court refused to credit those citations. || Misrepresented: Case Law | Defendants noted several incorrect/inaccurate citations in the Consolidated Complaint, including two cases cited over fifty times that did not support Plaintiffs' propositions; counsel's errata did not cure these inaccuracies. || False Quotes: Exhibits & Submissions | Plaintiffs' Opposition contained AI drafting artifacts and unchecked inserted text (e.g., 'Let me know when you’d like to proceed to the next section: Count Eight . . .'), evidencing unverified AI-generated material and potential false quotations in submissions.
- Why it matters now
- Leaving AI prompt artifacts in a filing is strict-liability malpractice — require a human proofread pass before any AI-assisted brief ships.
